OEM 1000349720A replacement filter cartridge

998720 Oil Filter Paper Core Cross Reference 1000349720A 998720 lubrication filter paper core cross-referenced with OEM part number 1000349720A is a high-efficiency oil filter insert customized for Weichai National VI emission heavy-duty diesel engines. Adopting multi-layer deep-pleated composite filter media, this filter core effectively captures metal wear debris, carbon sludge, oil oxidation precipitates and micro abrasive contaminants suspended in high-temperature engine oil. It maintains stable and unobstructed oil circulation under long-distance heavy-load transportation, high-temperature and severe working conditions, greatly reducing friction and abrasion of crankshaft, bearing bushes, cylinder liners and other core engine components, stabilizing engine power output and cutting abnormal fuel consumption. Manufactured strictly in accordance with original OEM dimensional standards and fully verified by IATF16949 filtration performance tests, this dual cross-reference filter core provides long-term comprehensive engine protection for logistics fleets and mining machinery, effectively lowering engine failure rates and overall vehicle maintenance costs.  Product Material Description: This 998720 / 1000349720A filter paper core uses high-density composite cellulose blended with ultra-fine glass fiber as primary filtering medium. The filter paper undergoes professional high-temperature oil-resistant resin impregnation treatment to prevent fiber shedding, softening and swelling after prolonged contact with hot lubricating oil. A thick rigid reinforced paper inner support tube is equipped to avoid pleat collapse under fluctuating oil pressure, matched with high-elastic NBR nitrile rubber sealing gasket featuring outstanding anti-aging and oil corrosion resistance. All raw materials comply with international heavy-duty automotive filtration standards, with uniform fiber distribution, balanced oil permeability and large dirt holding capacity.
